From my understanding, that’s actually what causes mammals to yawn. No idea why it seems ‘contagious’ though, obviously yawning is more of a voluntary reflex. So why is it that if you see someone else yawn, you’re likely to also yawn? 🤷♂️
That sounds like a combo reflex if you ask me, which actually does happen to me around 20 minutes after I take a vitamin B12 pill. I’ll get like all the reflexes all at once, sneeze, hiccups, coughing, urge to vomit, all at once. All from a vitamin B12 pill. Never again!
I never said it helped in any way, as a matter of fact the experience is absolutely miserable and painful when it happens that way. Not like hiccupping is a voluntary reflex ya know, just saying that having trapped gasses in my belly tends to trigger it sometimes.
When that happens to me, the best thing I can do to try to help is to lay down, and occasionally roll over on my left and right sides, until the gas finally finds it’s way out, usually via burping.
But yeah, these reflexes aren’t exactly voluntary.
